Final Technical Report: Advanced Measurement and Analysis of PV Derate Factors

King, Bruce H.; Burton, Patrick D.; Hansen, Clifford H.; Jones, Christian B.

The Advanced Measurement and Analysis of PV Derate Factors project focuses on improving the accuracy and reducing the uncertainty of PV performance model predictions by addressing a common element of all PV performance models referred to as “derates”. Widespread use of “rules of thumb”, combined with significant uncertainty regarding appropriate values for these factors contribute to uncertainty in projected energy production.
